In the embodiment of FIG. 9B, the first wireless ultrasound probe 101 may be wirelessly paired with the ultrasound diagnostic apparatus by using a WiFi communication scheme, and may perform data communication with the ultrasound diagnostic apparatus via 60 GHz mm wave short-range communication. Thus, the display 900 b may display the second UI 921 that is a GUI indicating WiFi, and the third UI 931 that is a GUI indicating a 60 GHz mm wave short-range communication scheme.

On the other hand, a text ‘Unknown’ may be displayed on an area of the thumbnail image of the second wireless ultrasound probe 102, and an icon indicating charging may be displayed on the thumbnail image of the second wireless ultrasound probe 102. This may mean that the second wireless ultrasound probe 102 that is not paired with the ultrasound diagnostic apparatus is being charged.

In the embodiment of FIG. 9B, the display 900 b may display the area of the thumbnail image of the first wireless ultrasound probe 101 to be highlighted by using a different color or applying a shadow thereto, the first wireless ultrasound probe 101 being paired with the ultrasound diagnostic apparatus.
